the starwars.com article is gone.

Try here: http://www.dvdactive.com/editorial/articles/star-wars-the-changes-part-one.html - missing a few visual differences I think, but comes with some unopinionated commentary.

Mod Edit: Unfortunately the website linked to above is no longer around. However, the Internet Archive’s WayBack Machine has a working functioning link for the site, here:-

The Star Wars website articles no longer linked to on the official website can be found here - kindly re-uploaded and compiled by doubleofive on his blog:-
